Scancell announces selection of COVID-19 vaccine candidate, SN14
SN14 offers several potential advantages over currently approved and late-stage COVID-19 vaccines
Scancell Holdings plc, (AIM:SCLP), the developer of novel immunotherapies is pleased to announce that they have selected their COVID-19 vaccine candidate, SN14, for further development and clinical trials. SN14 targets both the SARS-CoV-2 nucleocapsid (N) protein and the key receptor-binding domain (RBD) of the spike (S) protein, and is based on a modification of Scancell's ImmunoBody® DNA vaccine technology.
Fifteen vaccine candidates containing different S and N components combined with a variety of targeting technologies were evaluated for the best T cell and antibody responses. SN14 reproducibly elicited high-titre anti-S virus neutralising antibodies (VNAbs) together with high avidity T cells against both the S and N proteins. SN14 also incorporates Scancell's AvidiMab™ technology to further enhance this immune response demonstrating the broad potential of this platform technology to generate improved vaccines for both infectious diseases and cancer.
SN14 is a second generation vaccine which offers several potential advantages over currently approved and late-stage COVID-19 vaccines:
· Not only does SN14 target the S protein to induce VNAbs that prevent the COVID-19 virus from entering cells but also induces strong T cell responses to both the S and N proteins to destroy virally-infected cells and prevent further viral replication.
· As the N protein is well-conserved between coronaviruses, the SN14 vaccine has the potential to be effective against any variant or new strain of coronavirus in addition to the current COVID-19 strain.
· Use of the AvidiMab™ technology increases the potency of the T cell response which, in turn, should lead to long-term protection and immunological memory.
· DNA vaccines are exceptionally stable, do not require ultra-low temperature storage and are manufactured using relatively simple processes.
As reported in October 2020, Scancell entered into a collaboration with Cobra Biologics, part of the Cognate BioServices family, to conduct preliminary work leading to the manufacture of SN14 with the goal of starting a Phase 1 COVIDITY clinical trial as soon as possible during 2021. The project is funded by an Innovate UK grant awarded to a consortium between Scancell, the University of Nottingham and Trent University.
Professor Lindy Durrant, Chief Scientific Officer of Scancell commented:
"We are very excited about our SN14 second generation COVID-19 vaccine which could have significant advantages over first generation vaccines, either on its own or in combination with other vaccines to broaden and strengthen the immune response for long term protection".
